SPINDLE APPARATUS FOR RING-SPINNING AND LIKE FRAMES.

Application filed November 30, 1926, Serial No. 151,679, and in Great Britain February 24, 1926.

This invention relates to improvements in connection with the spindle apparatus to take the place of the usual fiyers, cap, and ring, and the like spindle apparatus, that is,

in that class of spinning frame where the the driven tube means for increasing the ease of running and consequently enabling an increase of speed to be obtained, and much larger bobbin to be employed.

My invention is in the nature of a bearing between what is known as a cap tube and the top of a solid spindle, from which bearing the tube is supported. The bearing may take the form of a ball interposed between the top of the spindle and an upper bearing fitting, carried by the tube, or the spindle may be coned to rest in a bearing carried by the tube, or the tube may carry a coned or pointed bearing member to takeinto a hollow in the spindle end or the top. Lubricating means Will be provided, the lower end of the tube or wharl portion will not bear on the base or rail. The ring used will be fixed as to position and the spindle will be carried 011 a lifter rail.

Referring to the drawings which form a part of this specification- Fig. 1 represents a sectional elevation of a tube on a spindle according to one form of my invention. v

Fig. 2 represents an elevation and plan of a top bearing referred to.

Fig. 3 represents a sectional elevation of a modified form of tube supporting device.

Fig. 4 represents a plan and sectional elevation of a modified bearing member.

Fig. 5 represents a plan of a suitable ring holding device, and

Fig. 6 represents a detail of a ring adjusting device.

To carry my invention into effect, the cap tube T which is carried by the Wharl W is continued upwards to or slightly beyond the top of the solid spindle S which latter is carried by a lifter rail L and the upper end of the tube is closed, preferably by a removable bearing piece B, and between this piece and the top of the spindle which is suitably shaped, I in one form (Fig. 1) mount a ball 0. Thus the spindle supports the ball, and the ball the tube, and the lower edge T of the tube T or wharl fitting dips into a 0 u 1 suitable, 011 well or reservoir C, but does not contact with the base thereof. Guard walls such as G may be carried either from the wharl, or Oll reservoir.

These walls may be stepped as at C to receive a dished Washer O placed above the lubricant to prevent same being forced out by centrifugal force and to act as a guide to return any oil from above the washer to the reservoir.

The tube T encloses the spindle S and the I latter may have a spiral groove or grooves G cut therein, one or more apertures or cuts T leading from the outer to the inner face of the tube towards the base in order to provide efficient lubricating means, although I do not confine myself to this exact form.

In Fig. 3 the spindle may be pointed or coned as at S and the bearing member B have a coned aperture B through which the point S may project.

The bearing member B and the tube and such as 13 preferably central, will be tormed to give passage for air, see Figs. 1, 2 and 4:.

The ring R is ofthe fixed type either carried by a rail in the ordinary manner, or preferably carried by a ring clip R, which clip is adjustably mounted by a spindle R in a bearing R suitably mounted in con nection with a fixed part of the machine. The clip R is divided as at R and is provided with securing means such as R By using a ring holder of this type, different sizes of rings may be quickly adapted. The bearing R may also be adjusted laterally, see F 6. p

Vith anti-frictioi'i devices of the kind described and supporting the tube from the top, the tube beii'ig driven around a dead spindle mounted on a lifter rail, steady running and increased speed as well as efficient spinning are obtained at all reason able speeds, whether they be high or low.

Large bobbins may be employed and increase of length of yarn produced without knots, further there is a considerable saving of time due to the periods of dofiing being less frequent, and there is a saving of time in the twisting and winding operations.

I am aware that it has been heretofore proposed to carry bobbins or live spindles on dead spindles by means of anti-friction bearings between the top of the spindle and bearings carried by the bobbin or live spindle. The spindles have generally been hollow and in some cases have been provided with external spiral grooves to assist lubrication of the bearings, whereas in my combination I combine with a dead spindle mounted on a litter rail, a driven cap tube supported on bearings from the top of the spindle, the tube operating within a sta- 20 tiona-ry ring and thus with one apparatus obtain the effect of ring, cap, or fly, spinning.

I claim v In a spinning frame, the combination of a lifter rail, a dead solid spindle supported thereby, a cap tube mounted for rotation on said spindle, a single bearing disposed between the spindle and the tube at their upper ends, said bearing communicating with the atmosphere, and an oil reservoir encircling a portion ofthe spindle and enclosing the lower end of the tube, said spindle being provided with a spiral groove communicating with said reservoir and adapted to convey oil from the reservoir to the hearing between the spindle and tube.

In testimony whereof I have signed my name to this specification.
